Solid-State Lighting Technical Requirements

DLC Premium Requirements

SSL V5.1Effective July 1, 2020

DLC Premium is a higher-performance classification for luminaires and retrofit kits. The Premium classification is intended to differentiate products that achieve higher energy savings while delivering light quality and controllability performance that exceed DLC Standard requirements. Products submitted to the DLC Premium classification must meet more stringent efficacy, quality of light, and controllability requirements.

Premium Requirements

This document describes the additional requirements for qualifying products under the DLC Premium Classification. These requirements must be met in addition to the requirements for Standard Classification.

How to Submit

Products submitted to the DLC Premium classification may be submitted in either a Single Product Application or in a Family Grouping Application. Single Product Applications may not contain products submitted to multiple classifications, multiple light output bins (for outdoor luminaires), or multiple primary uses.

If a manufacturer submits a family and only part of the family meets the DLC Premium classification requirements, the manufacturer will need to provide additional worst-case testing sufficient to demonstrate compliance of each part of the family group with the applicable requirements.

Updating Products to Premium

In order to update products on the QPL to the DLC Premium classification, manufacturers must create a new product application through the application portal. Manufacturers must submit the additional required information on driver ISTMT, safety certification, controls information, and L90 evaluation, along with a new application form and any other additional information not provided with the original application. Learn more about updating listed products to Premium Classification here.

Custom and integrated drivers must provide equivalent driver spec sheet documentation as drivers from third-party vendors. This also applies to private labeled drivers where the private labeler does not market the private labeled driver and therefore does not have a public-facing driver spec sheet for the driver. Equivalent driver spec sheet documentation must include information on the rated driver performance, including but not limited to: input and output characteristics, the maximum case temperature for which the driver is designed to last ≥50,000 hours, TMP location, as well as the specific driver model number. Reviewers may ask for additional driver information.
